flattened and-;laterally-extended. The free M My invention relates to'self lubricating travelers for use upon the vertical type of rings for spinning and twisting machines.

The essential objects of my invention are 5 to provide a reservoir for the lubricating grease capable of being supplied elsewhere than from the surface of the ring-where the lubricant is most needed; to insure at all times a constant and uniform supply of lubricant to, the ring; and to attain these objects in an inexpensive structure, and by-a simple methodiof construction. Other objects and advantages will be apparent to those skilled in the art. v

My invention consists in the structural features and in the method of construction defined in the appended claims.

In the accompanying drawings which disclose a characteristic vembodiment of my in- V vention,

Figure 1 is an isometric view of the original blank from which my traveler is formed,

' Figure 3, a section taken on linev 3-3 of Figure 2,

Figure 4, a perspective view of the same, and i a Figure 5, a front elevation'of my traveler shown in running position upon a spinning or twisting ring of the vertical type.

Similar reference characters indicate similar parts throughout the views. v

My traveler is formed from a blank 7 cut from a length of cylindrical hollow wire. The blank has cut in its wall near one end an orifice 9,-and diametrically opposed to the latter near the other end of the blank is an angular transverse 111015101111 of substantial depth intersecting the bore 13 of the blank. The described blank, shown in Figure 1 is next by suitable tools bent and compressed into a traveler of the form shown in Figures 2 to5 inclusive. In detail the traveler? com- 45 prises a vertical cylindrical body or shank 14 provided in its upper end with an orifice 9. Integral with the upper end of theshank is a laterally extending hollow longitudi nally angular horn 15 formed by compressing one end of the blank so that the horn is end [of the horn isrpreterably iclosed' by excessively compressingthe material at that point as at 17; Integral with the lower end of the shank isa substantially solid, laterally directed, lower horn19; The horn is laterally expanded by the complete compression of-the' endof the original blank into, asubstantially solid, nontubular form. This compression extends jfromithe apex of the incision "11' of theblank outwardly wherebythe lowerhalf'ofthejincision forms a resultant recess 21 in the lower horn, and the up:-

' per half ofthe incision forms adownwardly inclined boundary for the opening 23 atthe lower end of the shank. The latter opening forms the end of the enclosed lubricant reservoir comprising a portion 25 extending substantially the length of the shank, and a portion 26 continuous therewith in the upper horn 15. I The lubricant supply orifice 9 communicates with both portions of the lubricant chamber.

In Figure 5 is shown my traveler in runs ning position upon a vertical ring 28 and engaged by the thread 30 running from the rolls to the bobbin.

The grease is interjected through the orifice 9 until it fills or substantially fills the reservoir constituted by the portions '25 and 26. The frictional heat generated by the movement ofthe' traveler on the ring liquefies the grease which emerges from the mouth 23 of the reservoir or chamber and lubricates the side of the ring, and its lower edge which affords a bearing for the horn 19.

It will be observed that by the introduction of the grease into the reservoir of the chamber through the orifice 9 the necessity of initially smearing the ring with grease to be fed to the traveler and subsequently returning the liquefied grease to the ring is avoided.

' It will be further noted that both the traveler construction which enables the use of tubular wire, and the method of construction hereinde'scribed, contribute to facile and inexpensive construction;

1. A traveler for a spinning or twisting ring comprising a tubular shank provlded 1n- 7 its upper outer portion with an orifice for the reception of a lubricant, and in its lower inner portion with a discharge opening 'for the lubricant and horns upon the ends ofthe shank.

2. Atravelerfor spinning or twistingrings comprising a shank provided in its-upper outer portion with an orifice for the admissionofa lubricantg and inits lowerinner'portion with adischar ge opening, ahorn integral with the upper end of the shank, and a; horn integral with the'lower end of theshank, the.

shank and the first mentioned horn being" 7 provided with an enclosedchambencommnnieating with the orifice and openings.

3. A tra veler' vfor :Spinning or twisting rings comprising-a cylidrical tubular shank provided-with an orifice in its upper portion,

and in its lower portion with' adischarge opening, a horn of greater breadth than the diameter of the shank integralwith the upper end of the shankrand a horn of gre'ater width than'the diameter of the shank integral with the lower endof the shank." I c signature.
